To a, whom-it may-concern;

Be it known that I, HERBERT E. MAmsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State-of Illinois, have invented new and useful Improvements in Change-Makers, of which'the following is a s ecification.

The object of this invention is to provide a machine of simple and substantial construction embodying coinparatively few parts for accurately and automatically making change in multiples of five cents or in multiples of one cent. I

In the accompanying drawings I have illustrated one form in which the invention can be embodied, and, referring thereto, Figure 1 is a horizontal sectionalview on the line 1 1 of Fig. 2. Fig. 2 is a vertical sectional view on the line 2 2 of Fig.1.- Fig. 3 is a detail sectional view of the retracting slide-bar operated by a coil-spring. Fig. 4 1s a vertical sectional View on; the line 4 4 of Fig. 1'.- Fig.

Fig. 12 is a detail sectional view of the two-dimes ejector. Fig. 13 is a detail view of the threecents ejector. Fig. 14 isa perspective view of the five and fifteen cents keys, and Fig. 15 illustrates the keyboard of a machine embodying the invention and adapted to give the proper change when a key representing the amount of purchase is struck.

Referring to the drawings, 1 is a casing of any suitable shapeand size, within which is preferably contained all of the operative mechanism of. the machine with the exception of the key-levers, which project through an opening 2 in the front of the casing.

I will first describe the machine as constructedfor making change in multiples of five cent's and then describe the mechanism for making the'odd change.

The keys numbered in multiples of five from five to ninety-five are arranged in two rows one above the other for convenience in operation, the odd-numbered keys being preferably located in a plane above the evennumbered keys 4. Each of these keys is carried by a key-lever 5, Fig. 1, pivotally mount- Specification of Letters Patent.

Fig. 6 is a detailed betweenits ends on a rod 6 anchprojec'ting within the casing. The inner end of the keylever is pivotally connected by a'linku'Y to one arm. 8 of an angle-lever, which is. 'pivotally mounted on a rodd), Fig. 2. The other-farm 8 of'said angle-lever is pivotally'co ct'ed by a link 10 to a horizontal slide-bar tending from front to rear ofthe machiiie an'gl guided in'the guide-bars 12. The rods 6. 9 and the guide-bars are suitably supported, in the casing, and the guide-bars each comprise a bar 13, provided with slots 14, properly spaced apart by suitable partitions to acco mmodate the various slides, Fig. 6. The removable plate 15 holds the slide-bars in their proper place in the guides.

. Patented J's-1 24; 906.

To obtain the proper change in multiples offive cents, I provide five independent ejector mechanisms, one for half-dollars, one for quarter-dollars, one for nickels, one for single dimes, and onefor double dimes, these several mechanisms being mounted on a support 16, Fig. 7, within the casing. Each ejectormechanism comprises a slidable ejector 17, operating in channel-guides 18 of a -bed plate 23, fastened on the support 16., An

have shown a two-dimes-ejector mechanism which differs from the others only inithe re-' spect that the lower end of the holder 'is-cut discharge two dimes at one time, the ejector being shaped at its forward end to engage two 1 dimes for this pur osej I prefer to bevel the upper side of the orward end of the ejectorslide at 22, so that the ejector-slidemay bev more easily withdrawn from beneathj the stack of coins and so that the stack .ofcoins will be permitted to fall slowly to position on the bed 23. Each ejector-slide is provided on its under side with a toothedrackjz',

which projects downward through a slot in the support and meshes with a segmentgear 26, rigidlymountedjona rock-shaft. 27.

away at 21 suflioiently topermit the ejector to v upright coin-holder 19 is mountedin front of ing two dimes at one time, and in Fig, .12 I I The rock-shaft is supported in the casing and neath an derstood t at each key must be adapted through the medium of its slide-bar to rock those shafts which will operate the-ejectors tordischarge the proper amount of change.

In Figs. -1 to13 the keys represent the provided with hooks 29, suitably disposed'to engage the proper yokes for 0 erating'the ejector mechanismls which will ischar e the change designated by the key connec c "with said slide-bar. For exam le, the ve-cent key has its sllde-bar provi ed with one hook to on age theyoke of the rock-shaft associate with the nickel-ejector, and the ninetyfive-cent key has its slide-bar provided with 20 three hooks to "fzngaf e the yokes of the rockshafts associated w th the half-dollar, the quarter-dollar, and the two-dimes .ej ectors.

A retracting slide-bar 30 is guided in the guide-bars 12 and is provided with hooks 31 to engage all of the yokes, so that this re tracting slide-bar will "always be moved forward at each operation of a key whether one yoke or more than one oke is operated. This retracting slide-bar 1s under-constant spring-tension tending return it to normal position, and I may employ a leaf-spring 32,

ig. 2, or a coil-spring 33, Fig. 3, for this pur-i.

oose. As soon as the pressure 1s removed from the key the spring acting on the retracting slide-bar willreturn this bar and the yo'kes,which have been operated, as well as the entire-ejector II'ICGhiLDlSIIlSylZO their normal position at rest.

The forward and rearward movements of each ejector-slide are limited by the engagement of the rack 24 with the end Walls 34and 35 of the slot 25 in the support, .Figs. 7, 10. These end walls constitute sto s for the ejector-slide. I may also provi e a cushioned sto 36 to be engaged by the lever-arms 8', an to form an additional stop for limiting I the return movement of the several parts which are actuated by the keys I may provide an adjustable stop 37 in the form of a cross-bar located beneath the inner ends of the key-levers 5.

The coin-holders 19,"Fig. 9, are preferablyrectangular in cross-section andtmade intwo arts, one of which, 19, is fastened to the ed-plate 23 and the other, 19", of which is hinged to said part 19 A fastening device 3}? of suitable character is provided'to lock t e stac ed in the holder; I provide a sightopening 39 in the front of each holder and a window 40 in the front of the casing-,Fig. 4, so that the operat r'may readily ascertain when the coin-supply in any holder needs replenishing.

Themachine can be made, as shown in keys are a change to be delivered and each slid'e-barisparts together after the coins have been rigs, Hand-15, to deliverthe' pro er change b" striking-the key representing t e, amount diff-purchase. In th s construction there should be se arate.,rows ofkeys 51, 52,, and 53 tribe use to deliver change from dollars, half-dollars, and quarters, respectively, and asingle key to make change'ot adime 7 Thes lc'o'nnected up with the .yokes by the same means heretofore described, but in such a manner thatwhen a key representing the amount ofplurchase is struck change of the proper amount will be delivered. one a dollar is offered in payment for a fifteen-cent check, the fifteen-cent kev in the dollar row 51 would be struck and eighty-five cents change delivered. If a half ollar is'ofiered in payment of a fifteen-cent check, tbevfifteen-cent key in the half-dollar row 52-would ered: If a" quarter is oireredin payment of a fifteen-cent check, the fifteen-cent key in the quarterrow 53 would be struck-and tencent's ehange delivered. If ten cents is offered in e 54, wouldbe struck and five cents change de ivered.

Fi 15 illustrates diagrammatically a key boar of this character, and Fig.14 shows in detail the connectionsof the fifteen-cent keys of'the three rows and also the connections of the single five-cent key with the yoltes on the roc r-shafts, which rock-shafts operate the ejector-slides in precisely the same manner heretofore described.

To make change in odd cents'that is to say, in other amounts than exact multiples of five-I provide a series ofininor keys disple of five keys (which .r'nay be designated generally the major keys) and arranged to be operated simultaneously with the major key with which they are associated, as shown in Fig. l. I provide, preferably, four minor keys 41 for each major key and arrange them close to themajor key, so that any one of them, can be operated at the same time and. by the same finger used to operate the major key, or the minor key can be operatedby the middle finger at the same time that the major of the major ke e if occasion requires to deliver one, two, t ree, or four cents in change. The .minor keys are carried by ke -levers which operate slide-bars, and these slide-bars are associated with yok'es "on rock-shafts which carry toothed segments adapted to operate ejectoreslides, as heretofore described. Minorkeys maybeusedwith the majorkeys in the construction of Figs. 14, 15 in like manner.. I provide ejector mechanis'insfor discharging one cent, two cents, three cents, and four cents. The one-cent ejector 42 is like the half-dollar, quarter-dollar, nickel, and singledime ejectorsy The two-cents ejector 43 is payment oia five-cent check, the five-cent keyis operated by the forefin er.

'lhiis.ninety-live cents involving the operation. or the hall-dollar, uartm dollar, and two-dimes ejectors, will be delivered by the operation ol'a single key just as one nickel will be delivered by the operation of a single key, and the parts are of such a simple character that all the keys can be operated with no appreciable dill'er- 5o ence in ell'ort.

The distance between the pivot center and the gear and the length of the gear of each segment-gear is proportioned to the diameter of the coin which the ejector mechanism is designed to discharge. Thus the half-dollarejector mechanismwill have a largersegment adapted to travel in a greater are than the dimc-ejectors, so that the ejector-slide in I lee the tWO-(XJiiih and two dlmes e ectors to,

In fact, the denominations of the coins is wholly immaterial, as the machine can he employed to deliver coins of any denomination by properly proportioning the parts. i
